DETAILED DESCRIPTION

[0016] The present application is further described in detail hereinafter with reference to drawings and embodiments, the following embodiments are explanations to the present application, and the present application is not limited to the following embodiments.

[0017] Referring to FIGS. 1 to 4, a folding chair with armrests according to this embodiment includes a chair frame and a fabric provided on the chair frame. The chair frame includes a left crossed tube structure and a right crossed tube structure. The left crossed tube structure is formed by a first left crossing tube 11 and a second left crossing tube 12 crossed with and hinged to each other. The right crossed tube structure is formed by a first right crossing tube 13 and a second right crossing tube 14 crossed with and hinged to each other. The chair frame further includes two backrest tubes 31, two armrest tubes 32 and two armrest support tubes 33. Lower ends of the two backrest tubes 31 are respectively hinged to the first left crossing tube 11 and the first right crossing tube 13. Backrest sliders 34 are respectively sleeved on middle portions of the two backrest tubes 31, and the backrest sliders 34 are hinged to the second left crossing tube 12 and the second right crossing tube 14 respectively. One end of each of the two armrest tubes 32 is hinged to the respective one of the two backrest tubes 31, and an upper end of each of the two armrest support tubes 33 is connected to the respective one of the two armrest tubes 32. During folding, each armrest tube 32 may rotate with respect to the respective backrest tube 31 by taking one end of the armrest tube 32 as a pivot point, so as to be folded, and the normal folding function of the folding chair will not be interfered. The chair frame further includes a front crossed tube structure and a rear crossed tube structure. The front crossed tube structure is formed by a first front crossing tube 15 and a second front crossing tube 16 crossed with and hinged to each other. The rear crossed tube structure is formed by a first rear crossing tube 17 and a second rear crossing tube 18 crossed with and hinged to each other. A lower end of the first front crossing tube 15 and a lower end of the second left crossing tube 12 are both hinged to a first hinging seat 21. An upper end of the first front crossing tube 15 and an upper end of the first right crossing tube 13 are both hinged to a second hinging seat 22. A lower end of the second front crossing tube 16 and a lower end of the second right crossing tube 14 are both hinged to a third hinging seat 23. An upper end of the second front crossing tube 16 and an upper end of the first left crossing tube 11 are both hinged to a fourth hinging seat 24. A lower end of the first rear crossing tube 17 and a lower end of the first left crossing tube 11 are both hinged to a fifth hinging seat 25. An upper end of the first rear crossing tube 17 and an upper end of the second right crossing tube 14 are both hinged to a sixth hinging seat 26. A lower end of the second rear crossing tube 18 and a lower end of the first right crossing tube 13 are both hinged to a seventh hinging seat 27.

The second hinging seat 22, the fourth hinging seat 24, the sixth hinging seat 26 and the eighth hinging seat 28 are respectively fixedly connected to four corners of a seat fabric 4 for supporting a human body. Each of the two armrest tubes 32 has an armrest slider 35 fixed thereon, and the armrest slider 35 is provided with a sliding slot 351. An upper end of the respective armrest support tube 33 is slidably arranged in the sliding slot 351 of the armrest slider 35, thereby connecting the armrest support tube 33 to the armrest tube 32 by the armrest slider 35. Middle portions of the two armrest support tubes 33 are respectively hinged to the first left crossing tube 11 and the first right crossing tube 13. Two support tube slider 37 are respectively sleeved on the second left crossing tube 12 and the second right crossing tube 14, and the two support tube sliders 37 are respectively slidable on the second left crossing tube 12 and the second right crossing tube 14.
